The No-Hassle Projector
Does the cost and hassle of changing projector lamps and dust filters have you down? Acer’s K520 hybrid laser-LED projector has neither, which can save a lot of time and money over its lifetime. The trick is that rather than an expensive high-pressure lamp, the K520 uses a combination of laser and LED light to put 2,000 lumens in XGA resolution onto a screen. Able to fill a 25-foot screen, the K520 has ports for VGA, HDMI, component-, composite- and S-video connections. It can work with 3-D material and weighs in at 8.9-pounds. The K520 costs $1,600 and has an estimated life of 20,000 hours, or roughly 12.5 years of maintenance-free school use.
